Insight import UI displays wrong weekdays when using Cron Expression

Issue Summary

Insight import UI displays wrong weekdays when using Cron Expression.

Steps to Reproduce

1. Create an Object Schema
2. Create any Insight Import Configuration (CSV, Discovery or any other)
3. Tick "Automatically synchronize" and set the following Cron Expression
   

   0 27 12 ? * 3

   
   
4. Insight UI translates to 'At 12:27 PM, only on Wednesday'
   
5. Cron is triggered on Tuesday instead of on Wednesday

Expected Results

Insight UI should display 'At 12:27 PM, only on Tuesday'.
Wednesday field is 4 and Tuesday is 3

Actual Results

Insight Displays the wrong day (Wednesday) when the import will be triggered.

Workaround

Instead of using Day-of-week field, to avoid confusion, use for example, “MON,WED,FRI” in the day-of-week field. For this scenario would be:

0 27 12 ? * TUE
